"Hearing Analyzer Portrait" is a hearing health check tool that allows you to measure your hearing over a very wide range of audible frequencies.

The human ear possesses an auditory range from 20Hz to 20kHz. In addition to conventional audiometry (125Hz - 8kHz), the extended low-frequency audiometry and high-frequency audiometry including mosquito sounds are available. You can self-diagnose the sound listening ability.

By measuring the characteristics of your current hearing, please try to consider the wellness of your ears and the way of natural sound reproduction. It is possible to measure the hearing of the audio range by finding the minimum point in the operation of the volume slider where you can hear the test pure tone for each frequency. The results are displayed in easy-to-read graphs similar to an audiogram.

Recommended to check your own hearing ability on a daily basis for the audiophile, music players, sound professionals and all music lovers. Try to check if you have the golden ears!

Features:
- Broadband hearing test in 3 frequency bands: Lf (Low Frequency) - 30Hz to 100Hz, Std (Standard Frequency) - 125Hz to 12kHz, Hf (High Frequency) - 13kHz to 20kHz
- Test tones of Lf: 30, 40, 50, 60, 70, 80, 90, 100 (Hz)
- Test tones of Std: 125, 250, 500, 1k, 2k, 4k, 8k, 12k (Hz)
- Test tones of Hf: 13k, 14k, 15k,16k, 17k, 18k, 19k, 20k (Hz)
- Test channel: Left, Right
- Test tone type: Intermittent tone (Tone A) / Continuous tone (Tone B)
- Measurement result graph display (Level/Ath/Both): Linear level without ATH compensation (Level), ATH compensation (Ath)[*1], Both results (Both)
- Clear setting and results. (Reset)
- Snapshot of single band result. (Snap)
- Snapshot of full band result. (Snap-W)

*1: ATH (Absolute Threshold of Hearing)
ATH is also known as the hearing threshold and is the minimum sound pressure level of pure tone that can be detected on the hearing in noise-free environment. Human is said to be able to listen from 20Hz to 20kHz, but the sensitivity of the hearing will vary greatly depending on frequency. ATH varies with age and sex, but is a good sensitivity at mid-range (1kHz - 5kHz), and needs more greater sound pressure level at a lower and higher frequency. In the Lf and Hf frequency bands, the information in the ATH graph is for reference only.

Notes:
- This app does not support all wireless headphones and only supports Bluetooth (A2DP) headphones. If you cannot confirm the connection, use wired headphones.
- This app generates a test tone signal with a high gain, so please special attention to the volume adjustment.
- Before the diagnosis start, please set the hardware volume control to the central position of 50%. If you move the volume slider upward, the output volume will have a large gain. So as not to be excessively large gain for your ears, please adjust it carefully. 
- The classification of the hearing ability refers to WHO.

Remarks:
In general, a high risk of hearing loss has been known if you continue to hear the sounds of a high acoustic pressure level, such as, listening of the portable audio and working with too loud noises. We hope that you will continue to take an interest in your hearing health on a daily basis through this app. If you feel the need to manage the health of your ear, it is recommended that you see a medical professional.
